Octane

Generally speaking, the higher the octane, the greater the performance of the fuel. Tesco 99 Octane has an octane rating of 99 RON minimum and 87 MON minimum.

RON (Research Octane Number) is a historic knocking test undertaken at low engine stress and temperature levels which reflects modern turbo engines.

MON (Motor Octane Number) is a knocking test taken at higher engine stress and temperature conditions which reflects all performance cars.

Bioethanol

A renewable component made from crops. It is very high octane while also being free of pollutants such as sulphur and aromatics. We have found that in motorsport the addition of 5% bioethanol substantially improves power from a turbo engine.

And not many olefins

Olefins in petrol can lead to the creation of deposits which can cause engine damage. Tesco 99 Octane is naturally low in olefins.

How did Greenergy get involved?

The idea to create Tesco 99 Octane first came about when Greenergy MD Andrew Owens’ tried adding 5% bioethanol to the race fuel he was using for rallying to see if it had any impact on performance.

The result was higher torque and more power.

He also found that the bioethanol was great at cooling the engine charge and causing the inlet temperature to drop remarkably, thus giving the overall effect of having a bigger, more efficient engine in the car. To find out more listen to Andrew’s podcast.
